Hi Michal, Thank you for your response!
We know we can enable the RPC by changing the configuration file of the ofplugin-li. However, it is difficult for VTN project to accept the migration to the OFP-Li with this way. In this way, to use VTN project's features, user need to manually stop the controller, change the configuration file manually, and start the controller again. And, I don't think there is a way to enable the RPC in runtime. Therefore, we would like your team to provide the "get-flow-statistics-from-flow-table" RPC by default in the OFP-Li. Or we would like your team to provide applications (e.g. VTN project's features) with a way to enable the RPC in runtime.
